Determination of coolant content in plant tissues
Phenolic substances in plant tissues are oxidized to Da by polyphenol oxidase, and Da can automatically polymerize into colorful substances and browning occurs.
Measurement of vitamin C content
Vitamin C is one of the most important vitamins in human nutrition and a deficiency can lead to scurvy. Fruits and vegetables are the main source of vitamin C f
Experiments on the effect of potassium ions on stomatal openings
The expansion and contraction of the guard cells on both sides of the stomata directly affects the opening and closing of the stomata, which significantly influ
Determination of ascorbic acid content
Ascorbic acid, i.e. vitamin C, is widely found in fresh fruits and vegetables, and it is a highly active substance involved in many metabolic activities. Ascorb
Determination of nitrate reductase activity
NO3- taken up by plant roots must be metabolically reduced before it can be further utilized by the plant. Nitrate reductase (EC.1.6.6.1, abbreviated as NR) is
Solution culture of plants and observation of deficiency diseases
Essential elements are mineral elements that are necessary to maintain the normal physiological activities of plants. To determine whether various elements are
Assay of nitrate reductase activity
Nitrate reductase is a key enzyme in the metabolic action of plant nitrogen and is associated with the ability of crops to take up and utilize nitrate nitrogen.
Effect of growth hormone analogs on root and shoot growth
Growth hormone and its synthetic analogs have a great influence on plant growth, but different concentrations produce different physiological effects. The effec
